Custom serverless runtime image

Overview

This example shows how to create own custom runtime for a serverless Function based on the Python runtime and debian:bullseye-slim base image to provide support for glibc.

Prerequisites

• Docker as a build tool

Build an example runtime

1. Export the following environments:

   export IMAGE_NAME=<image_name>
   export IMAGE_TAG=<image_tag>

2. Build and push the image:

   docker build -t "${IMAGE_NAME}/${IMAGE_TAG}" .
   docker push "${IMAGE_NAME}/${IMAGE_TAG}"

   Note: You can use it to define your Functions in Kyma. To learn more, read how to override runtime image.
